At this point, I could rewrite all the skill echoes so it's "Bob jumps out of the way of your totally awesomely executed boneshatter." to be the analogue of a save, but that sounds like less fun than reading the telephone book.

Or I could add saving throws to ignore a bunch of the skills. You hamstring someone, but damn it, they make the save and they're not bleeding and don't take any damage.

None of this sounds like fun to do, and none of it sounds like it would make the game better.

I respect your opinions on a lot of aspects of the game; the way melee classes balance out vs. mages isn't one of them anymore, if ever it was.
